INSTALLING THE  IRM

3-8

2. Attach the female end of an AUI cable, no more than 50 meters in 

length, to the transceiver.

3. Attach the male connector on the AUI cable (3, Fig. 3-4) to the AUI 

port (2) on the IRM.

4. Move the slide latch (1) on the AUI Port to secure it to the lock post 

on the AUI connector.

3.4.2

Connecting to the Network Via the BNC Port

To connect to the network via the BNC Port:

1. Attach a BNC tee-connector (2, Fig. 3-5) to the BNC port (4) on the 

module.

2. Attach the thin-net segment (1) to one of the female connectors on the 

tee-connector.

NOTE: Each segment attached to the tee-connector must be terminated. 
If a segment is not attached to one of the female connections on the 
tee-connector, then a terminator must be placed on that connection.

3. Attach another thin-coax segment (3, View A) or a terminator (5, 

View A) to the other female connector on the tee-connector.
